In attendance were Bosnia's top officials, public celebrities, and foreign diplomats.
Addressing those gathered, the current chairman of the country's tripartite presidency, Bosnian Serb representative Nebojsa Radmanovic, said the Dayton agreement was, however, a great success, also from the present-day perspective.
Radmanovic admitted that Bosnia now needs changes and that they must be a result of democratic agreements and cooperation between elected political representatives of all the three constituent peoples (Bosniaks, Croats and Serbs).
The Dayton deal has elicited strong criticism over recent years as it created new administrative divisions in Bosnia, enabled non-typical constitutional solutions and slowed down decision-making processes in the political and economic spheres.
